“Well then, mendicants, listen. The mendicant Moggallāna has become so powerful and mighty by developing and cultivating the four bases of psychic power. What four? Moggallāna develops the basis of psychic power that has immersion due to enthusiasm … energy … mental development … inquiry, and active effort. He thinks: ‘My inquiry won’t be too lax or too tense. And it’ll be neither constricted internally nor scattered externally.’ And he meditates perceiving before and behind: as before, so behind; as behind, so before; as below, so above; as above, so below; as by day, so by night; as by night, so by day. And so, with an open and unenveloped heart, he develops a mind that’s full of radiance. The mendicant Moggallāna has become so powerful and mighty by developing and cultivating these four bases of psychic power. And by developing and cultivating these four bases of psychic power, the mendicant Moggallāna wields the many kinds of psychic power … controlling the body as far as the realm of divinity. … And by developing and cultivating these four bases of psychic power, the mendicant Moggallāna realizes the undefiled freedom of heart and freedom by wisdom. And he lives having realized it with his own insight in this very life due to the ending of defilements.”
